Answer:
Explanation:
given,
mass of the girl (m₁)= 45 kg
mass of the plank(m₂) = 147 kg
constant velocity of girl relative to plank = 1.53 m/s
velocity relative to ice berg(v₁) = ?
conservation of momentum
momentum of system = 0
hence, the velocity relative to ice berg is 1.17 m/s
They travel at the same rate of speed
Answer:
The same number of atoms of each element must appear on both sides of a chemical equation. However, simply writing down the chemical formulas of reactants and products does not always result in equal numbers of atoms. You have to balance the equation to make the number of atoms equal on each side of an equation.
